Big rigs are common on Southland freeways, thanks in part to the Los Angeles/Long Beach port complex, and a report released Thursday found that Los Angeles County is home to two of the country’s top 15 truck bottlenecks.

The 60 Freeway interchange with the 57 Freeway in Diamond Bar ranked fifth on the list. The 710 Freeway at the 105 Freeway in the Paramount/Lynwood area came in at number 13.

“California not only is our nation’s most populous state, but with our farms, key ports and border crossings it is our gateway to the world’s markets, making it a key state for the trucking industry,” California Trucking Association CEO Shawn Yadon said in a statement. “Congestion costs trucking billions of dollars and harms our economy. ATRI’s report makes clear where the biggest issues lie and we urge policymakers to quickly address them with much needed investment.”

Atlanta’s “Spaghetti Junction” — the interchange of interstates 285 and 85 North — ranked as the most congested freight bottleneck in the country.

The 15 Freeway at state Route 91 in Corona ranked 45th on the list, while the 110 Freeway at the 105 Freeway came in at number 64. The 10 Freeway interchange with the 15 in San Bernardino came in 27th. Two interchanges in Oakland also placed in the top 65.

The rankings are based on GPS data from more than 800,000 heavy-duty trucks and include an assessment of truck congestion at 300 locations across the country.
